The purpose of this study is to explore factors that influence the use of intercity-bus services by means of applying a structural equation model. The data were collected by a questionnaire survey based on personal interviews with intercity-bus users in Chungcheongnam-do province. Analysis results show that environmental attributes of the bus service are more important than operational attributes. In the case of men, the cleanliness of bus stops and the ease of transportation card recharging are likely to be the most crucial factors. However, women are likely to consider the cleanliness of the bus as the most important factor affecting their satisfaction about the intercity-bus service. Moreover, as people's satisfaction about the bus service increases, their willingness to recommend the use of intercity-bus to others will increase. Therefore, to improve the use of intercity-bus and to increase the satisfaction about the service, clean buses must be provided. These results could contribute to developing a policy to activate the use of intercity-bus.

메타버스는 인공지능, 블록체인, 네트워크, 가상 현실, 착용 가능한 기기 등 수많은 현대 기술들이 발전하면서 서로 융합되어 생성된 대규모 디지털 가상화 세계이다. 현재 메타버스 기반 다양한 플랫폼들이 대중화되면서 산업계 및 연구계에서는 메타버스의 발전에 주목하고 있으며, 긍정적인 시장 전망을 예상하고 있다. 하지만, 아직까지 메타버스 세계에서 발생할 수 있는 보안 위협 요소 및 대책에 관한 연구는 상대적으로 부족하다. 메타버스는 새로운 패러다임의 컨텐츠 및 서비스를 제공하고, 기존 IT 환경에서보다 방대하고 예민할 수 있는 사용자의 데이터를 요구하며, 여러 IT 기술들이 결합된 시스템인 만큼 고려해야 할 보안 위협 요소들이 많다. 본 논문에서는 메타버스 아키텍처를 소개하고, 사용자의 이용 환경, 가상 환경 및 디지털 트윈 환경에서 발생할 수 있는 보안 위협 요소들에 대해 제시하면서, 이에 대해 메타버스 서비스 제공자, 사용자 및 관련 제도 관리자들이 고려할 수 있는 대책들에 대해 소개한다.

Most of people still use the bus, which is one of transportation. But the space of cauch station where the passengers wait for the bus is still not enough for them in effect. Therefore, the space is analyzed through looking into the behaviors occurred in the waiting space .So, this paper defines the a primary factor affecting environmental from the existing environment and experience behaviors occurred in the existing environment, and suggests design guideline based on data and information from the result when redesigning.

The purpose of this paper is to provide a convenient platform for bus users and a platform to provide tourist services suitable for bus tourism as integrated services. Recently, the number of FIT tourists for recreational purposes using public transportation is increasing as the bus use environment is improved. Accordingly, we need a tourist platform that meets the needs of tourists. In particular, a bus information providing algorithm is implemented using a bus information public API to more conveniently use the bus information providing system, and a user use behavior data collection module and a data mining module To develop a contents platform based on a bus stop for bus tourism services to FIT tourists using public transportation.

This study analyzed that the impact of the bus use environment on users' stress in each step of bus use, from accessing to leaving to transfer, in the city of Daejeon. For this, we collected the stress data from 300 users using personal interviews at the bus stops and on-board bus. Also, we used factor analysis and structural equation model method for analysis of the impact of external and internal bus environments on stress of users. The results of this study showed that the highest stress impact factor was an onboard factor(${\beta}=.416$) including 'density and crowding', 'no seat to seat' and 'low ride comfort and safe'. The next stress impact factor was transfer factor including 'insufficient transfer information', 'lack of connectivity of bus and subway' and 'uncomfort transfer route'. From the above, we recommend that bus policies need to focus on not the supplier but users and also, this user based policy need to be more specified considering the characteristics of various users such as females, the elderly, irregular users, and so on.

To improve bus service quality and passengers' safety at bus stops, it is necessary to analyze the relationship between bus stopping behaviors and bus stop conditions. Thus, this study investigated the proper stopping rate at 31 bus stops on Central Boulevard in Busan metropolitan city and analyzed the relationship between the proper stopping rate and bus stop operating conditions such as the length of berth, the distance from the front line of berth to bus shelter and so on. The analysis results show that the proper stopping rate is 45.82 % and the rates are closely related to each bus stop operating condition. Therefore, it is highly recommended that the front line of berth should be located parallel to bus shelter for improving the safety of bus passengers. In addition, it is suggested that the length of berth should be longer than 15m and the pavement marking of berth be redesigned with dash lines to take account of buses' entering and leaving the berth.

오늘날 공장 자동화에 이용되는 필드버스 네트워크는 설러 가지가 있으며 이들은 각각의 미디어 접근 방식과 프로토콜을 사용하고 있다. 서로 다른 종류의 네트워크는 완전히 분리되어 있기 때문에 네트워크 관리자는 이를 관리하는데 많은 어려움을 겪고 있다. 본 논문에서는 이러한 이기종의 필드버스 네트워크를 통합할 수 있는 통합 필드버스 게이트웨이를 설계하였다. 통합 필드버스 게이트웨이는 이더넷 프로토콜을 이용하여 다른 네트워크로 데이터를 전달할 수 있고 프로토콜간의 변환을 수행하여 분리된 네트워크를 통합하고 통합된 환경으로 제어 및 모니터링을 가능하게 한다.

Currently, the Metaverse is introduced in various fields, and a virtual convergence economy that uses NFTs for content or item transactions is expected to develop into a 'metaverse environment'. The 'metaverse environment' will lead the changes in our society in the future and it will be fused with AI, big data, cloud, IoT, block chain, and next-generation network technology. However, personal information, device information, and behavior information provided by Metaverse users to use the service are subject to major attacks. Therefore, in order to provide a safe environment for users to use and to expand the business base of related companies, building a public-private cooperation system and developing a security guide are the leading tasks. Therefore, in this study, we compare and analyze metaverse features and technologies, and examine possible security threats and countermeasures.

COVID-19 is forcing people to minimize face-to-face networking activities between members of society, and they are increasing their use of online platforms. In particular, interest in the metaverse, a virtual community with enhanced realism, is growing. Specifically, this study suggests a mechanism to improve the intention to continuous use of metaverse users by using the self-determination theory, and confirms that trust between metaverse members moderates the relationship between self-determination and intrinsic motivation. We obtained 353 samples through a questionnaire targeting those who have used metaverse and verified the hypothesis through structural equation modeling. As a result of the analysis, individual self-determination of the metaverse formed intrinsic motivation such as identification and enjoyment, which affected the intention to continue use, and the trust of metaverse members partially moderated the relationship between self-determination and motivation. The result contributes to the sustainability of the metaverse platform by suggesting an approach to users and the environment to improve the intention of continuous use of metaverse.
